Text description provided by the architects. Rather than demolishing an ageing 1970s timber house, Japanese studio HYAN chose to inherit it — renovating the building into a home and studio for its own founders in the hills of Hayama, Kanagawa. Built in the late 1970s, during the development of a hillside residential district behind Hayama's former imperial villa area, the house belonged to Japan's pre-1981 seismic-code generation.
